Default CoolerMaster Hyper 212+ performance on i7

Does anyone have any temperature numbers running a Hyper 212+ on an Intel i7 processor?

I just went from a Q6600 with a Hyper 212 (original) to an i7 920 with the Hyper 212+. The temps seem quite a bit higher on the i7, but it's also quite a bit more power as well (285W vs 190W at the plug). I had done some custom ducting on the Q6600 and put the fan outside the case pulling air through the fins. The Q6600 was running 2.4GHz (stock), but I have bumped the i7 to a 166MHz bus which puts it at about 3.48GHz under load.

Anyway, I'll do some more testing / tweaking and see if I can get the temperature spread down a bit.

Here's the initial results using OCCT 3.1.0 on Windows 7 64bit.
Settings are: Linpack, 64 bits, Hyperthreading



Q6600 Pass 1 (min / max / delta)
=========================
C1 - 36 / 58 / 22
C2 - 36 / 58 / 22
C3 - 33 / 48 / 15
C4 - 30 / 48 / 18


i7 Pass 1 (min / max / delta)
=====================
C1 - 40 / 80 / 40
C2 - 39 / 79 / 40
C3 - 39 / 75 / 36
C4 - 37 / 73 / 36


i7 Pass 2 (min / max / delta)
=====================
C1 - 42 / 80 / 38
C2 - 40 / 80 / 40
C3 - 41 / 75 / 34
C4 - 39 / 74 / 35


- CPU and heatsink base are lapped to 400 grit and quickly polished with Brasso
- case is open
- thermal compound is Arctic Cooling MX-2

1) Do NOT use Brasso to polish your heatsink or CPU. It is a polishing compound and will hurt thermal transfer, not help it. Clean off both surfaces as best you can and don't apply anything other than thermal paste.
2) Those temperatures seem perfectly normal for an i7 CPU.
3) What program are you using to monitor your temperatures?

1. I use Brasso to even the finish. Without it, the aluminum / copper will bite into each other (sharp peaks) and this actually reduces the overall surface contact. If the unpolished surfaces are moved while in contact you can actually damage the surface (galling) which will act as a wedge.

The surfaces were cleaned before applying the MX-2. I hadn't even thought of using Brasso as a TIM. :)


2. Yes, I agree. After doing the test while monitoring the power draw it seemed to make sense.


3. OCCT saves results as graph image (or CSV if you choose), but I was also using the Stability Monitor in Everest 5 as it keeps track of the Min / Max / Avg values.

What revision do you have, what is your Vcore, your VTT, your ambient room temperature, what case do you have and how many case fans do you have?

These are all factors to how cool or how hot your i7 920 will run.
Mine for instance is a C0/C1 so it runs hotter then a D0. I can't remember my VCore or Vtt at the moment but my ambient room temp ranges from 20-27C provided on the weather outside and/or AC. I am running the CM690 with all the fan slots filled as well as running a dual fan config on my Hyper 212+.

Temps i get at full load at 3.8GHz with dual fan config at ambient temp of 25C is about 77C tops (full load tests were done with protein folding which stresses the cpu more then any other testing program).
Temps i get at full load at 3.8GHz with dual fan config at ambient temp of 20C is about 60C

It's a D0 revision with a Core Voltage of 1.240V (says CPU-Z). All voltages are set to default or Auto in the BIOS. As I mentioned above, the case is open so extra cooling fans probably won't make much of a difference unless they're helping to push more air through the 212+ fins. I'd be interested to see what your core temperature deltas from idle to full load.

I'll check out the protein folding software (Folding@home?) and see how the temps and power draw compares to the Linpack results.

I'll probably run something again to let you know, do you run just the stock heat sink fan on it, or do you have it like i do in a push/pull configuration (one fan pulls air across the heat sink, the other one pulls air off of it)

Should note i use Real Temp for my temperature readings as they seem to be the most accurate for i7s

Right now the Hyper 212+ is stock aside from the lap and polish. At some point I'll probably pressurize the case and setup the stock fan as a ducted-puller like I did on the Q6600 system. I'd like to do some tests to verify if there is any advantage to horizontal / vertical orientation of the heatsink (fan blowing towards the top or towards the back of the case).

Thanks for the tip on Real Temp, I'll look into that as well.

for an overclocked i7 the temps are ok.

that hs is great for the money, but at the high end will fall short a few crucial degrees. go higher(crazy volts) and the top dow will further distance itself. the design wasnt made to take more than that..:)

Your temps are fine. For 212+.
